Automated tests commonly upload screenshots or videos upon failure or retry to test runs, however, there is currently no option to delete these videos after a certain duration, and this will require manual intervention.
Use case: I'll run a regression weekly and upload failures if occurred, but I won't need 4 year old v2 attachments when i'm running out of space on v200.
E.g. In settings there could be a toggle "Automatically delete attachments" and when enabled, a "days" textfield or picker appears (default 7 or something)
